Just fishing for a few ideas. Zwei is outside, as usual, with the flock, in the day pen, safe and sound as far as I can tell. But for the last 15 minutes or so, she's been giving the staccato honk that is usually given when there's no food. Funf has occasionally done, this, too. The other ducks are standing around, not doing much, not standing at attention but not behaving as if they are relaxed. I checked the house and veranda - doesn't look like anything's there or recently has been. I did fluff things around making sure of that before I let them into the pen/house area. It's mild - about 50F, and raining lightly. There are crows calling and flying about 250 feet away, perhaps harassing a hawk or cat. So, I'm asking myself: Hormones? (It's late autumn here) Annoyed that they're closed in the pen? Is she calling to the crows? Bored? Does she smell or sense a predator that is lurking nearby? We have a long list of predators, which is the reason she's in the day pen with the door shut while I spend a little time indoors (I spent a few hours with them outdoors this morning, and I got fairly moist and chilly).
